Yes, one of Aura's known moves is Bubble. Though obviously it's not a combat move, she is capable of doing some pretty fun things with it... like blowing hearts

Not that it works on everyone... especially a certain lucario Rone... who just seems to find Aura annoying....

Oh well.... try harder Aura

The Guardian of the North Wind

Is Aura. why is she called that? it's simple. She appears to be the guardian of a legendary sword called "Northwind" A wind/ice-element sword that grants the wielder some control of the weather... or so the legend goes.

It can be shrunken down at will to a small hair-pin that aura wears in her hair. Sometimes she wears it on the outside as a fasion statement.... other times. she hides it in her hair. Though to most people it just looks like a strange sword-shaped hair-pin.

It is notable that Aura is not proficient in the use of swords (and seems to have no interest in learning to use it for some reason) so interestingly enough she doesn't use the sword in combat.
